First, we found the volume and mass of the aluminum block. The volume was 8cm^3, and the mass was 22.515 grams.
We found that the density of the aluminum block was 2.851875 g/cm^3. We found the volume and the mass of the copper cylinder. To find the volume we used a graduated cylinder and it came out to 6cm^3, the mass was 56.25g.
The density of the copper cylinder was 9.375g/cm^3

The rod and the cylinder are both made of the same material, copper. The screw and the block are both made of aluminum. We know that the block and the screw are the same material because the density of the block was 2.9g/cm^3. The density of the screw was 2.7g/cm^3. The density of aluminum is 2.7g/cm^3 and they are both right near it.
We found that the density of the aluminum block was 2.851875 g/cm^3.
